#!/bin/bash
# install centos7 or rhel6.5
read -p "please select what version do you want to install, centos7 or rhel6.5: " version
if [ "$version" = "centos7" ]
then
    echo "===*stop firewalld,NetworkManager,selinux*==="
    systemctl disable firewalld
    systemctl disable NetworkManager
    setenforce 0
else
    echo "===*stop firewalld,NetworkManager,selinux*==="
    chkconfig iptables off
    chkconfig NetworkManager off
    setenforce 0
fi
